Auditory brain stem evoked responses (ABRs) in children with delayed speech (DS)—A Diagnostic Problem

The results of analysis of auditory brain- stem evoked responses (ABRS) are reported in 173 patients with delayed speech (DS). The mean age of the patients is 4.6 years (age ranges from 1.4 years to 10 years). The patients were classified into 5 groups based on ABR findings:

Galectins - potential targets for cancer therapy

Galectins are a family of galactose binding lectins that have become the focus of attention of cancer biologists due to their numerous regulatory roles in normal cellular metabolism and also because of their altered levels in various cancers. They are reportedly similar to several prominent and established modulators of apoptosis. In this review, we present a brief outline of the advancements in the methodology used to detect and identify them and their therapeutic applications in cancer. Their possible interactions with other glycoconjugates are also discussed and a vision for their future use in diagnosis and therapeutics is provided.     

Expression of CD163 in the liver of patients with viral hepatitis

CD163 is a marker of activated macrophages, and increased levels of soluble CD163 have been detected in sera obtained from patients with hepatitis. The aim of this study was to detect the expression of CD163 in the liver from patients with viral hepatitis. Frozen sections of liver specimens were obtained from 5 patients with acute viral hepatitis (AH) and from 23 patients with chronic viral hepatitis (CH). The expression of CD163 in the liver was determined immunohistochemically using monoclonal antibody to human CD163. Double immunostaining was done to assess those cell types that express CD163 in the liver. The frequencies of CD163-positive cells were significantly higher both in the portal areas and in the hepatic lobules in the liver of patients with AH compared to those with CH (p < 0.05). Double immunostaining revealed that most of the CD163-positive cells were macrophages and Kupffer cells, because they expressed CD68. The expression of CD163 was very low in endothelial cells and liver stellate cells. This study shows that macrophages are activated in hepatitis liver.     

In the footsteps of senning: lessons learned from atrial repair of transposition of the great arteries

The Senning operation has evolved from being the initial surgical correction that allowed survival in complete transposition of the great arteries to an integral part of the anatomic repair of congenitally corrected transposition. In patients with complete transposition, the Senning operation has given satisfactory initial and long-term surgical results, but the potential for right ventricular failure and atrial arrhythmias have drastically reduced its indications in the current era. The long-term follow-up and pertinent postoperative issues of the Senning operation will be reviewed, along with its newfound role in the anatomic repair of congenitally corrected transposition.     

In vitro effects of new generation fungal derived nitric oxide donors on rabbit basilar artery

The fungal derived nitric oxide donors, (E)-ethyl-2-[(E)-hydroxyimino]-5-nitro-3-hexenamide (FK409) and N-[(E)-4-ethyl-3-[(Z)-hydroxyimino]-5-nitro-3-hexen-1-yl]-3-pyridinecarboxamide (FR144420), were evaluated for the treatment and prevention of cerebral vasospasm induced by subarachnoid hemorrhage (SAH) by an in vitro study using rabbit basilar artery. The tension-relaxation of a 3 mm-long artery segment was carried out in a micro-tissue organ bath with a real-time recorder to record the tension-relaxation curve. Steady contraction of the specimens was induced by KCI (n = 12) and oxyhemoglobin (oxyHb) (n = 12). Sodium nitroprusside was used for comparison. Each of the agents was added in ascending concentration. Relaxation caused by FK409 and FR144420 was significantly greater (p < 0.05) than that by sodium nitroprusside. Relaxation effects of FK409 and FR144420 on the KCl-induced steady contraction were better than those on the oxyHb-induced contraction. FK409 and FR144420 have potential uses for the treatment and prevention of SAH-induced cerebral vasospasm.     

Clinical pattern of ocular manifestations in vitiligo

To study the ocular abnormalities in cases of vitiligo, 100 patients were examined who underwent a series of investigations e.g., complete haemogram, urine analysis, blood biochemistry and chest x-ray and 70 cases were taken as control. Patients with systemic diseases such as diabetes mellitus, thyroid and auto-immune disorders were excluded. Detailed ocular examinations including recording of vision, slit-lamp biomicroscopy, gonioscopy, ophthalmoscopy and examination of fundus by 90 D lens were done. Of 100 vitiligo patients, 23% showed hypopigmented sports on the iris, 18% pigmentation on anterior chamber, 9% retinal pigment epithelium hypopigmentation, 5% uveitis, 11% had chorioretinal degeneration and 34% had no ocular findings. There lies a strong association of ocular disorder in patients with vitiligo.     

Drug induced hepatic focal nodular hyperplasia

Focal nodular hyperplasia, an uncommon benign hepatic tumor, has been reported following ingestion of various drugs and chemical agents. The authors report a case of a young girl who developed such lesion following ingestion of antituberculosis drugs for the treatment of her abdominal tuberculosis.     

Impact of health education and screening over all-cause mortality in Japan: evidence from a cohort study during 1984-2002

BACKGROUND: Health education and screening are two components of preventive health services in Japan since 1983. This study investigated their relationships with all-cause mortality as they are studied insufficiently in Hokkaido, Japan. METHODS: This study enrolled 1,532 men and 1,653 women aged 40-97 years from 1,702 randomly selected households of 60 areas during 1984-1985 and followed them until 2002. At baseline survey, staffs of 45 health centers collected sociodemographic, medical, behavioral, and dietary information including health education and screening from study subjects with informed consent. RESULTS: For men, age-adjusted Cox proportional hazard model indicated lower mortality for those who received health education (RR = 0.76, P < 0.01) and screening (RR = 0.83, P < 0.05) than those who did not. Health education showed lower mortality even after adjusting for many variables. Similarly for women, health education (RR = 0.66, P < 0.01) and screening (RR = 0.64, P < 0.001) revealed lower age-adjusted mortality. Almost similar results were found for both services when models were adjusted for many variables and when the deaths including lost to follow-up cases of the first 4 years of baseline survey are excluded. CONCLUSIONS: This study shows protective effects of health education and screening over all-cause mortality for both sexes. However, further studies are needed to confirm the results.     

Control of nasal obstruction in perennial allergic rhinitis

PURPOSE OF REVIEW: Nasal obstruction, the cardinal symptom of persistent (perennial) allergic rhinitis, is one of the most common symptoms encountered in primary care and in specialist clinics. It is difficult to quantify by clinical examination, and, hence, objective assessment of the nasal airway is critical to rhinologic research. Nasal obstruction in persistent allergic rhinitis must be treated the year round, and therefore treatment choices, costs, and compliance all become important public health issues. RECENT FINDINGS: Many inflammatory and neurogenic mediators released during allergic reactions are able to cause plasma exudation and vasodilatation, with resultant edema and swelling of the nasal mucosa. Recently, technological advancements have made it possible to qualitatively and quantitatively study the nasal airway, providing greater insights into the understanding of physiological fluctuation and pathophysiological manifestations of nasal patency. From recent international guidelines, the management of allergic rhinitis includes combining treatments of the upper and lower airways, by using patient education, allergen avoidance, pharmacological treatment, and specific immunotherapy. Surgery may be needed as an adjunctive intervention. Multiple methods have been introduced to treat turbinate hypertrophy. However, preservation of adequate nasal mucosal function is important, together with long-term results. SUMMARY: It is important that consensus recommendations for the management of allergic rhinitis be designed and implemented by all levels of medical specialists in order to improve treatment outcomes.
